Show HN: Fast Chladni figure simulation in Python with NumPy vectorization

This Python code (Chladni_Figures.py) simulates the nodal line patterns of Chladni figures, approximating Ernst Chladni’s 1787 experiments with vibrating plates by modeling the resonant modes of a square membrane. It captures the visual essence of these wave patterns without simulating the complex physics of elastic bending and the dynamics of particle motion.
